The Skirmish at the Hidden Jedi Temple was an incident taking place during the Second Imperial Civil War in 137 ABY. A group of Imperial Knights fought with Jedi Knights of the New Jedi Order in their Hidden Temple.
Having witnessed the massacre on Mon Calamari and an Imperial patrol nearly killing his extended family, Cade decided that the only way to end everything and for the galaxy to leave him alone, was to kill Darth Krayt.
Upon arrival at the Temple, Cade was surprised to see Imperial Knights, Marasiah Fel, Antares Draco, and Ganner Krieg. He and Shado Vao immediately engaged the latter two. He ended the skirmish by Force pushing the two.
